To all inkom 'it may concern:

Be it known, that I, HYMAN E. MARKLE,

citizen -of the United States, residing at' Nashville, in the county ofDavidson and State of Tennessee, haveV invented certain new and usefulImprovements in Multiplex Graphophones, of'which the following is aspecification.

This invention is an improvement on the machine shown in my applicationiled August 27, 1906, Serial Number 332,224.

The object of my present invention is to simplify and improve themechanism shown in my former application; a further object ot .myinvention is to@v provide a machine of this character wherein thebringing of the successive records into playing position does notmaterially increase. the work on the motor and consequently I am enabledto use f a-motor, spring or electric, of the size that wouldordinarily'be used in a singlel record -maehine; and with these andminor' objects inlview my invention consists in the parts andeombinationof parts aswill be hereinafter more fully set out. f A In. the drawinFigure 1 is a front elevatiou of a multiplex graphophone embodying myinvention; Fig. 2 is a top plan view of the same; Fig. 3 is a sideelevation; Fig. 4 is a 'detail elevation, partsbeing in section; Fig.`5is edetail elevation of part of the carriage returning mechanism; Eig. 6is a detail viewof a slight modification ofthe magazinejwhcel; Fig'. 7is a detail view of a modiiication of part of the .drivingmech-l anism;Eig. 8 is a detailv view of the carriage'elevating pawl. e

l represents 'a suitablebaseupon which standards -2 are secured.. Aframe is mounted uponthe top'of said standards and` secured thereto by.means of ethe bolts or screws' 4.' .One of the side'mexnbers of theframe is 4depressed at. itsv center as at 5 which. permits of the readyreriioyalI of a cyl-l inder record from the magazine l wheel'.

Suitableibearings 6 are hung lfrom the frame'- 3 in which the magazinewheel is jour. naled. The magazine wheel is of.--spi`dej construction,-the spokes on one side c )f"tl'l`e wheel having hinged members8"which:a'1"e"-V kept in locked position by means of the 10is thecarriage rod and 11 the ifeed screw mounted inthe frame?) toward therear of the machine.

12 is the return or repeating screw mounte near the front of themachine.I

`vd3 is 'a gear casing in which is'journaled a suitable gear'train. v.

14 is the bandorpower wheel connected by means of a shaft 15 to the geartrain.

1 6 is the reproducing carriage having a suitable slide 17 mounted uponthe rod 10. 18 are feed nuts adapted to engage the feed screw 11. Thesenutslare mounted upon spring rods or stems 19, which in turn are;

mounted upon the slide 17 and secured thereto by means of the screws 20.

421 is a rod or bar secured near the front of the machine adapted tosupport the front end of thev reprodueer carriage -16. This bar or rodis provided with an elongated slot 22 to be hereinafter referred to. The-carriage 16 is provided at its front end with lugs 23 and 24 betweenwhich is pivoted an arm 25, said arm depending from the carriage andprovided with a shoulder 26.

This arm is provided with a pin 27 adapted to contact' with the pin 281n theA lug 23, whereby the arm .is'prevented from falling back towardthe center of the machine, thusinshring the arm at all timesdependingfrom the .front of the carriage.

29 `is a double oam.mounted upon a earriage by means ofthe screw '30,said double andy'32. This double cam, when in the positions shown rinFigs. 4 and 5, permits the' "front of the carriage to rest directly uponthe bar or' rod 21. If for any reason, such as transferring records, itis desirable toraise the front of the carriage, the double cam isswu-ng'up'on its pivot whereby one of the cam faces 1s brought intoengagement with the rod 21, thereby eleva-ting the front vof thecarriage. 'Ifthe carriage is raised without the-aid of this cam lthelarm 25 has' 4a tendency to swing inward until its shoulfder 26 restsupon the top of the bar 21.. When the cam 29 is used the pin 27 of the85' vcam being provided with operating pins 3.1

',slot 3G.

arm is engaged by one of the cam faces, l whereby it is prevented fromengaging the f rod 21.

is a tootlnbar depending from the front of the carriage and providedwith the tooth 34, which is adapted to engage, under certain conditions,the return or repeating' screw l2. v

is an arm extending from one Side of the front of the carriage over thebar 21, said arm being provided with an elongated 37 is a llatwhooksecured upon the arm 35 byV means of Vthe set screw 38 which passesthrough the elongated slot 3G. This hook is provided with lugs 39betweenA which is pivoted a stop40. By ineans of the stop l am enabledto limit the movement of the carriage by reason of the fact that it isad-A justably mounted through the 4medium of the flat hook 37 and theslot 3G. The carriage is provided with a loose-ly hung pawl 41 having anelongated slot 42 in which a screw 43 is secured tov limit the sidemoveinent oit said pawl. The pawl in Fig. S is normally pressed from thecarriage toward one side by means of the flat spring 44.

45 is a cam mounted upon the right hand end of a repeating or Areturnscrew l2. Any suitable means may be employed to lock said cam at anydesired point on the screw 12 according to the length of the record tobe reproduced.

ln the operation of the machine the carriage is fed toward the right andas the end ofthe record is approached the pawl v41 contacts with the cam45, but, by reason of the flat spring 44 and the slot 42, said pawl isadapted to give until the limit of compression of the spring 44isreached, when, the friction between the two parts is sufficient toenable the pawl to climb the eccentric when the lowest point of the:eccentric is reach-cd, vwhereupon the energy stored up-in spring 44causes the pawl 41 to slide upon, the periphery of the-eccentric. l yreason of this lateral movement ol the paw] it is adapted. to have awide point of contact with the ccentric, whereby it is In'ev'imted ,11and the tooth 34 is in engagement t'rmn :medentajlly slipping ofi'I ofthe eccentric. ,Ys soon as the pawl is in engagement with` the highestpoint of the eccentric or cam, the Vfront. of the carriage is elevatedand the arm '2:3 permitted, by gravity, to fall against the bar 21,whereupon the shoulder 2li rests upon the top of the bar 21. f ln thisposition of the carriage the .tending nuls 18 are disengaged from thefeedscrew th the repeat or return bar 12Q, v`Themachine V Continning.torun in thefonvard diretionf tion by the' carriage isreturnedfto itsinitial :posi-Q the screw 12 and when approaching the starting point thearm 25 is forced outward by contact with the trip 46 set at an angle tothe bar 21, until the shoulder 2G is pulled from the top of the bar 21,where upon the carriage is free to descend in contact with its feedscrew for repeatilnr a record or reproducing a new record. 'lbhis trip46 is adjustably secured in the elongated slot 22 of the bar 2l wherebythe depression ofthe carriage may be varied.

I have found that heretofore the carriages upon being. dropped intoengagement with the feed screw at the initial starting point, havefrequently damaged vor broken the records, therefore, it is my intentionto use the butler 48L at this point', said buffer being i connected to asuitable piston 47 mounted in the cylinder 48, said piston having a ballvalve 49.

50 is the shaft of the magazine wheel upon which is mounted a bevel gear51, which is adapted to be engaged by a bevel gear 52 keyed to the shaft53. On the end of the shaft 53 is a ratchet .wheel 54.

:sol

is a dog suitably mounted on the frame of the machine.

5G is a pin to liinit'the'upward movementV of the dog 55.

57 is an arm loosely hung from the shaft 53. There are two of thesearms, one on each side of the ratchet wheel 54.

58 is ay pawl having a counterweight 59, said pawl being pivotallymounted between the arms 57 in posi-tion for engagement with the ratchetwheel 54'.

G0 is a link pivoted to the arms 57 and to the lower end of a lever G1,said lever being provided with a handle (5,2 near its upper end. T hislever is pivoted at (i3 and is -provided at its upper end with a slot G4througl'l which the arm 35 of the carriage passes in the forwardmovement of the carriage.

G5 is a platey secured -to the top ofthe frame and provided with anelongated slot through which the lever 61 extends.

v'66 is a plate secured upon the plate (35 and provided with forked ends67, which register' with each side of the elongated slot in ,the plateG5.

(58 -is a bellcrank 'lever pivoted at (59 to the top of the frame 3, oneend ofV which extends between the plates 65 and 66, as clearly showninFigs. 1 and 2, and is adapted to `contact with the lever 61. ZO andv 71are two forked end p imposed, the forked ends of plates superwhichSpaced apart in order that the other arm of tween thnv t 72is a'bracketupon which 'a lever 73 is pivoted, the upper end of said lever beingLthe bell' cranklever G8. may freely move bepositioned in the forkedends of the plates the other end to one of the arms 75, whereby' thenormalv position of the arm 75 is in engagement with theends 77 of thewheel-arm. The lower end of lever 73 is forked and adapted'forengagement with one of the arms 75.

When the carriage is at the initial position on the record thelever- 61is in the position shown in Fig. 1. As the carriage is fed along therecord the hook 37 and the arm 35 pass through the slot 64' in the upperend of the leverA 61, until the pawl 41 engagesthe periphery of the camor eccentric 45, whereupon the front of the carriage is elevated by saidcam and the arm and hook i raised to a point above the slot 64 in thearm 6l. -The tooth 34 is now in engagement with the return screw 12 andas the carriage is fed in the return direction the hook 37 engages` theupper end of the lever 61 and pulls it toward the left hand side of themachine. As 4the carriage is moving toward the right handsi-de of themachinel and the hook 37 has passed through' the slot in the upper endof. th'e lever 61, the arm 40. engages the lever above the slot 64 andforces said lever toward the right of the machine thus drawing, throughthe link 60, the awl 58 into engagement with another toot lon theratchet wheel 54. The lever is now practically in a perpendicularposition. As the lever is being pushed to the perpendicular position itengages'the bell crank lever 68, thereby operating the lever 73v andforcing the arms 75 out of engagement with the magazine wheel.- As themachine is being returned to its initial position by means of the screw12, the Aarm 40 moves the 'lever toward the left of the machine a slightdistance and the hook 3 7 following engages the lever above .the slotJ`64 and `forces 'it toward the left of the machine without 1turther entheleft of the machine'until the a'rm of the movement of the lever is belowthe hook whereuponthe hook is free to movettoward gagementI with thelever., The lever in being, forced towardlthe left of the machinerevolves the shaft 53.one tooth of the ratchet wheel 54,-by memns'oftheweighted 'pawl 58.

' This movement, through the bevel gear wheels 5f-aire 52l evolves emagazine ing reproduce wheel a suiicient distanceto bring the nextsucceeding record in position under the stylus of the reproducer,whereupon the arms 7 5,`under tension of the spring 78, snap intoengagement with the outer ends of the arms of the wheel, thus holdingthe wheel against revolution while the record is be- During a certainperiod of the movement of the lever 61 the arms 75 are out of engagementwith the magazine wheel,

but the reverse movement of the wheel is prevented by Treason of the dog55 engaging the ratchet Wheel 54.

8() is a sprocket wheel mounted upon the shaft 50T" 81 is a framemounted upon the top of the :trame 3 at the rear, in which is journaledavolved, which, by means of the-chain 88, re'- volves the sprocket wheel87, whereupon the shaft 82 and the indicator 84:v are simultaneouslyrevolved with the ma azine wheel and the number of the record eingreproduced is indicated 'through 4the opening 85 in the hood 86.

As soon as the twelve records are played or reproduced and itis desiredto. reload-the .machine the lock is removed from the hinged end of thearm of the wheel, said hinged arm being thrown down into the depressionor yoke 5 in one of the sides of the frame 3,

whereupon the record may be removed from the cylinder immediatelyopposite said yoke or depression. The successive cylinders are movedinto this position until the wheel is reloaded with new records.

While I have shown the magazine wheel adapted for twelve records itwill, of course,

be understood vthat in practiceI mayinak'e"-iY it to hold three, six,nine or twelve records, more or less.

' The shaft 89 having the knob 90 or han-A dle is adapted for connectionwith the Inotor (not shown), whereby themotor may be started -orstopped. f

It is my intention to have an ornamental wooden case around the machineextending upto the frame 3.

In Fig. 6 I haveshown a sli ht modification of the construction of t emagazine wheel, by nieans 'of which I am enabled to dispense with thespokes on one side of the shaft upon which the cylinders 91 are mounted..Naturally the size of the shaft on which the cylinder is mounted wouldbe increased in thls construetlon lnasmuch the. outer end of the shaftWill not have a support. f

In Figi 7 I have shown a Wormas a substitute for the shaft 53. In caseswhere I elect to use the worm inplace of the shaft i i 5ml/Will omit thedog 55 inasmuch as the *"wormf'will besuilicient to prevent a backwardmovement of the magazine wheel.

In the event that it is not desired torel peat a record" tlie'arm l0 isthrow-nback shown.

from the position shown in Fig. 2, but in all cases when itis desired torepeat the same record the arm is thrown into the position shown inFig.,2.

The object of mountingthe nuts 18 on the spring arms 19k is to protectthe thread on the rod 11. For instance, inthe event that the carriage islet down at the `beginning of a record insuch position that the threadin thenuts-` does not exactly registerwith the.

thread on the rod `11, the nut may, byresiliency of the arm, give andautomatically adjustitself to said thread, besides which slight wear inthe thread of the nuts and the rod is taken up by the resiliency ofthese arms.

The trip i6 determining the depression of the carriage after its returnto the beginning ofa record and the hook 37 determinlng the automaticreturn of the carriage being mounted in elongated slots are adjustableto accommodate records of different lengths.

I amaware 'that slight changes may bel made in the details ofconstructionwithout departing from thespirit of my invention, and hence,I would have it understood that I do not wish to be limi-tedfto thedetails That I claim and desire to secure by Letters Patent is 1.
